The requirement C is vague and needs more clarification from the customer. It does not specify which public cloud provider, service, or storage tier should be used for the backup data. It also does not indicate how the backup data should be transferred, secured, or managed in the public cloud. The other requirements are more clear and specific, and can be met with the Veeam solution features and best practices.
